Structure for controlling water emission of pistol nozzle

Abstract

A pistol nozzle is provided with a water emission controlling structure which is located at the water outlet of the main body of the pistol nozzle and is formed of an adjusting member and a shaft having a water emission hole. The shaft is actuated by the adjusting member to displace so as to align the water emission hole with a sleeve which is located between the main body and the nozzle head of the pistol nozzle. The amount of water emitted by the pistol nozzle depends on the extent to which the water emission hole of the shaft is aligned with the sleeve.

I claim:  
     
       1. A water emission controlling structure comprising: 
       a pistol nozzle having a main body with a water conduit extending therethrough, said water conduit having a water outlet in communication therewith, said pistol nozzle having a nozzle head through which said water outlet extends, said pistol nozzle having a sleeve positioned between said main body and said nozzle head, said sleeve having a washer;  
       an adjusting member of a U-shaped construction and having two arms, each of said two arms having fitting hole formed therein;  
       two locating members each having a locating block;  
       a shaft having a generally spherical portion formed centrally therealong, said spherical portion having a water emission hole, said shaft having retaining grooves formed adjacent respective opposite ends thereof, said shaft having protrusions extending outwardly from respective opposite ends of said shaft, each of said protrusions having a retaining hole formed therein; and  
       two washers respectively retained in said retaining grooves of said shaft, said shaft being disposed in said water outlet, said spherical portion of said shaft being in intimate contact with said washer of said sleeve, said protrusions of said shaft being retained respectively within the fitting holes of said adjusting member, said adjusting member and said shaft being retained by said two locating members such that the locating blocks are retained respectively in the retaining holes of said protrusions of said shaft, said shaft being rotatable by said adjusting member so as to align said water emission hole of said shaft with said sleeve.
